(450) + (28.75x) = 967.50
solve for x

Answers

Answer 1

Answer:

x=18

Step-by-step explanation:

Answer 2

Answer:

x= 18

Step-by-step explanation:

To solve this equation you have to work backwards

Start by dealing with the numbers that we know:

450 + (28.75 × x) = 967.5

-450                          -450

28.75x = 967.5

(when a number and a letter in mathematics are next to each other they are multiplying)

Now divide to find the value of x:

967.5 ÷ 28.75 = 18

18 is the value of x

A company is reviewing a batch of 25 products to determine if
any are defective. On average, 3.1% of products are defective.
Does this situation describe a binomial experiment, and why?
What is the pr

Answers

The probability that the company will find 2 or fewer defective products in this batch is approximately 0.995. The probability that 4 or more defective products are found in this batch is approximately 0.005. The decision to stop production would depend on various factors and cannot be determined solely based on finding 5 defective products.

Yes, this situation can be described as a binomial experiment. A binomial experiment has the following characteristics:

It consists of a fixed number of trials or observations.Each trial has only two possible outcomes, success or failure.The probability of success remains constant for each trial.The trials are independent of each other.

To calculate the probability that the company will find 2 or fewer defective products in this batch, we need to calculate the probabilities for each possible outcome (0, 1, and 2 defective products) and sum them up.

Let's denote the probability of finding a defective product as p, which is 3.1% or 0.031 in decimal form.

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)\\P(X = 0) = C(25, 0) * p^0 * (1 - p)^{25 - 0}\\P(X = 1) = C(25, 1) * p^1 * (1 - p)^{25 - 1}\\P(X = 2) = C(25, 2) * p^2 * (1 - p)^{25 - 2}[/tex]

Using the binomial coefficient formula C(n, r) = n! / (r!(n - r)!), we can calculate these probabilities:

[tex]P(X = 0) = C(25, 0) * 0.031^0 * (1 - 0.031)^{25 - 0}\\ = 1 * 1 * (0.969)^{25}\\ = 0.643\\P(X = 1) = C(25, 1) * 0.031^1 * (1 - 0.031)^{25 - 1}\\ = 25 * 0.031 * (0.969)^{24}\\ = 0.295\\P(X = 2) = C(25, 2) * 0.031^2 * (1 - 0.031)^{25 - 2}\\ = 300 * 0.031^2 * (0.969)^{23}\\ = 0.057\\P(X \leq 2) = 0.643 + 0.295 + 0.057\\ = 0.995[/tex]

Therefore, the probability that the company will find 2 or fewer defective products in this batch is approximately 0.995.

To calculate the probability that 4 or more defective products are found in this batch, we can use the complement rule:

[tex]P(X \geq 4) = 1 - P(X \leq 3)\\P(X = 3) = C(25, 3) * 0.031^3 * (1 - 0.031)^{25 - 3}\\ = 2300 * 0.031^3 * (0.969)^{22}\\ = 0.040\\P(X \geq 4) = 1 - P(X \leq 3)\\ = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3))\\ = 1 - (0.643 + 0.295 + 0.057 + 0.040)\\ = 1 - 0.995\\ = 0.005[/tex]

Therefore, the probability that 4 or more defective products are found in this batch is approximately 0.005.

If the company finds 5 defective products in this batch, it does not necessarily mean that they should stop production. The decision to stop production would depend on various factors such as the acceptable level of defects, the cost of production, the impact on customer satisfaction, etc. It would require a more comprehensive analysis to make a decision in this regard.

Complete Question:

A company is reviewing a batch of 25 products to determine if any are defective. On average, 3.1% of products are defective. Does this situation describe a binomial experiment, and why? What is the probability that the company will find 2 or fewer defective products in this batch? What is the probability that 4 or more defective products are found in this batch?

evaluate the iterated integral by changing to cylindrical coordinates. 0 −1 √1 − x2 −√1 − x2 1 xy2 dz dy dx 0

Answers

To evaluate the iterated integral ∫∫∫ R x[tex]y^{2}[/tex] dz dy dx over the given region R in cylindrical coordinates, we first convert the limits of integration and the integrand to the cylindrical form. Then we evaluate the integral using the appropriate transformations and calculations.

In cylindrical coordinates, we express points in three-dimensional space using the variables (ρ, θ, z), where ρ represents the distance from the origin to a point projected onto the xy-plane, θ denotes the angle measured counterclockwise from the positive x-axis to the projection of the point onto the xy-plane, and z represents the height of the point above or below the xy-plane.

To evaluate the given iterated integral, we begin by transforming the limits of integration. The outermost integral corresponds to the variable ρ, which ranges from 0 to 1. The next integral corresponds to θ and remains unchanged since the region R does not involve any angular restrictions. The innermost integral corresponds to z and ranges from the lower limit of √(1 - [tex]x^{2}[/tex]) to the upper limit of √(1 - [tex]x^{2}[/tex]), as determined by the given limits of integration.

Next, we convert the integrand, [tex]xy^2[/tex], to cylindrical coordinates. The variable x is replaced by ρcosθ, and y is replaced by ρsinθ, giving us [tex]ρ^3cosθsin^2θ[/tex].

With the limits of integration and the integrand expressed in cylindrical coordinates, we proceed to evaluate the iterated integral. Following the order of integration, we integrate ρ from 0 to 1, θ from 0 to 2π, and z from √(1 - [tex]x^{2}[/tex]) to -√(1 -[tex]x^{2}[/tex]). The integration of ρ yields [tex]ρ^4[/tex]/4, the integration of θ results in 2π, and the integration of z simplifies to 0.

Finally, we substitute the limits of integration and perform the calculations: (∫(0 to 1) [tex]ρ^4[/tex]/4 dρ) * (2π) * (0). Evaluating the integral of[tex]ρ^4[/tex]/4 yields 1/20, and multiplying this by 2π and 0 gives us the final result of 0.

Therefore, the evaluated iterated integral in cylindrical coordinates is 0.

3(1+x2)dy/dx=2xy(y3-1)

Answers

If differential equation is 3(1+x^2)dy/dx = 2xy(y^3-1) then exponential is |y^3-1| = Ce^(x^2).

To solve the given differential equation, we can begin by separating the variables. We divide both sides of the equation by 2xy(y^3-1) to get:

3(1+x^2)dy/dx = 2xy(y^3-1)

(3(1+x^2))/(2xy(y^3-1)) dy = dx

Next, we integrate both sides with respect to their respective variables. On the left side, we integrate with respect to y, and on the right side, we integrate with respect to x:

∫(3(1+x^2))/(2xy(y^3-1)) dy = ∫dx

After evaluating the integrals, we obtain:

ln|y^3-1| = x^2 + C

Where C is the constant of integration. Finally, we can exponentiate both sides of the equation:

|y^3-1| = e^(x^2+C)

|y^3-1| = Ce^(x^2)

Here, Ce^(x^2) represents the constant of integration. Since the absolute value can be positive or negative, we consider both cases and solve for y to obtain the general solution.

determine if the described set is a subspace. assume a, b, and c are real numbers. the subset of r3 consisting of vectors of the form a b c , where a=b=c

Answers

The subset satisfies all three conditions, it is a subspace of [tex]R^{3}[/tex].

To determine if the described set is a subspace, we need to check if it satisfies three conditions: closure under addition, closure under scalar multiplication, and contains the zero vector.

Let's consider the subset of [tex]R^{3}[/tex] consisting of vectors of the form (a, b, c), where a = b = c.

Closure under addition: Let (a₁, b₁, c₁) and (a₂, b₂, c₂) be two vectors in the subset.

Their sum is (a₁ + a₂, b₁ + b₂, c₁ + c₂).

Since a₁ = b₁ = c₁ and a₂ = b₂ = c₂, we have (a₁ + a₂, b₁ + b₂, c₁ + c₂) = (a₁ + a₁, b₁ + b₁, c₁ + c₁) = (2a₁, 2b₁, 2c₁).

Since 2a₁ = 2b₁ = 2c₁, the sum is also in the subset.

Closure under scalar multiplication: Let (a, b, c) be a vector in the subset and let k be a real number.

The scalar multiple k(a, b, c) is (ka, kb, kc). Since ka = kb = kc, the scalar multiple is also in the subset.

Contains the zero vector: The zero vector is (0, 0, 0). Since 0 = 0 = 0, it is in the subset.

Therefore, the subset satisfies all three conditions, it is a subspace of [tex]R^{3}[/tex].

Answers

The function [tex]√(x^3 - 8)[/tex] at each x value is 0.25 * [-1.902 - 1.609].  The interval [2, 3] into subintervals and apply the respective formulas.

To approximate the integral ∫[2 to 3] √(x^3 – 8) dx using the Trapezoidal Rule, Midpoint Rule, and Simpson's Rule, we need to divide the interval [2, 3] into subintervals and apply the respective formulas. Let's compute the approximations for each rule.

Step 1: Determine the subinterval width, h.

We can calculate h using the formula:

h = (b - a) / n

Given:

a = 2

b = 3

Let's use different values of n for each rule.

For Trapezoidal Rule, let's set n = 4.

For Midpoint Rule, let's set n = 4.

For Simpson's Rule, let's set n = 2.

Step 2: Compute the approximations for each rule.

Using the Trapezoidal Rule:

Approximation = (h / 2) * [f(a) + 2f(x1) + 2f(x2) + ... + 2f(xn-1) + f(b)]

For n = 4:

h = (3 - 2) / 4 = 0.25

Approximation = (0.25 / 2) * [f(2) + 2f(2.25) + 2f(2.5) + 2f(2.75) + f(3)]

Evaluate the function √(x^3 - 8) at each x value:

f(2) ≈ √(2^3 - 8) ≈ -2

f(2.25) ≈ √(2.25^3 - 8) ≈ -1.726

f(2.5) ≈ √(2.5^3 - 8) ≈ -1.414

f(2.75) ≈ √(2.75^3 - 8) ≈ -1.125

f(3) ≈ √(3^3 - 8) ≈ -0.464

Approximation = (0.25 / 2) * [-2 + 2(-1.726) + 2(-1.414) + 2(-1.125) + (-0.464)]

≈ (0.125) * [-2 - 3.452 - 2.828 - 2.25 - 0.464]

≈ (0.125) * [-11.994]

≈ -1.49925

Using the Midpoint Rule:

Approximation = h * [f(x1) + f(x2) + ... + f(xn)]

For n = 4:

h = (3 - 2) / 4 = 0.25

Approximation = 0.25 * [f(2.125) + f(2.375) + f(2.625) + f(2.875)]

Evaluate the function √(x^3 - 8) at each x value:

f(2.125) ≈ √(2.125^3 - 8) ≈ -1.902

f(2.375) ≈ √(2.375^3 - 8) ≈ -1.609

f(2.625) ≈ √(2.625^3 - 8) ≈ -1.335

f(2.875) ≈ √(2.875^3 - 8) ≈ -1.073

3. Find the measure of arc JK.
Hint - arc LK is a semi-circle!
Find JK

A) 90
B) 116
C) 128
D) 130

Answers

Answer:

Option C

Step-by-step explanation:

We will analyze the figure and note down the properties given in the figure,

1). LK is a diameter so this line (chord) divides the circle into two arcs measuring 180°.

m(arc LJK) = m(arc LK) = 180°

2). m(∠JKL) = 28°

Therefore, by the property inscribed angle and intercepted arcs,

Intercepted arc (JL) = 2 × (Inscribed angle JKL)

m(arc JL) = 2(26°)

               = 52°

Now we will use these two points to get the measure of arc JK.

m(arc JK) + m(arc LK) + m(arc JL) = 360°

m(arc JK) + 180° + 52° = 360°

m(arc JK) = 360° - 232°

                = 128°

Option C will be the correct option.

To determine which polynomial is prime, we need to check if it can be factored into simpler polynomials or if it is irreducible.

Let's analyze the given polynomials:

3x^3 + 3x^2 - 2x - 2

3x^3 - 2x^2 + 3x - 4

4x^3 + 2x^2 + 6x + 3

4x^3 + 4x^2 - 3x - 3

To determine if these polynomials are prime, we need to check if they can be factored further. If they cannot be factored into simpler polynomials, they are considered prime.

The polynomial 3x^3 + 3x^2 - 2x - 2 can be factored as (x + 1)(3x^2 - 2).

The polynomial 3x^3 - 2x^2 + 3x - 4 cannot be factored further.

The polynomial 4x^3 + 2x^2 + 6x + 3 can be factored as (2x + 1)(2x^2 + 3).

The polynomial 4x^3 + 4x^2 - 3x - 3 can be factored as (2x + 1)(2x^2 - 3).

Based on the factorizations, the only polynomial that is prime (cannot be factored further) is 3x^3 - 2x^2 + 3x - 4.

Therefore, the polynomial 3x^3 - 2x^2 + 3x - 4 is prime.

Solve the following initial value problem. cos^2 (x) sin x dy/dx + (cos^3 (x))y = 5 ; y(π/3) = 4

Answers

The solution to the initial value problem [tex]cos^{2xsinx}dy/dx + cos^{3(x)}y = 5, y(\pi/3) = 4[/tex], involves solving the given differential equation and applying the initial condition.

To solve the differential equation, we can use an integrating factor. The integrating factor for the given equation is [tex]e^{\int{cos^3x} \, dx}[/tex]. Integrating [tex]cos^3(x)[/tex] gives us (1/4)(3sin(x) + sin(3x)).

Multiplying the entire equation by the integrating factor, we get [tex](1/4)(3sin(x) + sin(3x)) * cos^2(x)sin(x) * dy/dx + (1/4)(3sin(x) + sin(3x)) * cos^3(x) * y = 5 * (1/4)(3sin(x) + sin(3x))[/tex]

Simplifying, we have [tex](3sin(x) + sin(3x)) * cos(x)sin^2(x) * dy/dx + (3sin(x) + sin(3x)) * cos^3(x) * y = 5 * (3sin(x) + sin(3x))/4[/tex]

This equation can be rewritten as [tex]d/dx[(3sin(x) + sin(3x)) * cos^2(x) * y] = 5 * (3sin(x) + sin(3x))/4[/tex].

Integrating both sides with respect to x, we obtain [tex](3sin(x) + sin(3x)) * cos^2(x) * y = 5 * (3sin(x) + sin(3x))/4 * x + C[/tex], where C is the constant of integration.

Applying the initial condition y(π/3) = 4, we can substitute x = π/3 and y = 4 into the equation to find the value of C.

By substituting the values, we get [tex](3sin(\pi /3) + sin(3\pi/3)) * cos^2(\pi/3) * 4 = 5 * (3sin(\pi/3) + sin(3\pi/3))/4 * (\pi/3) + C[/tex]
